What is the best way to improve the fuel efficiency of an Audi A4?

I recently purchased an Audi A4 and I am looking for ways to improve its fuel efficiency. What are some tips or modifications that can be done to achieve better MPG?

One simple way to improve fuel efficiency is by keeping your tires properly inflated. This will reduce the resistance, resulting in better fuel economy. Also, make sure to regularly change your air filter to improve engine performance.

Consider using a fuel injector cleaner to remove any buildup in your fuel system. This will help your engine run more efficiently and use less fuel. Additionally, try to avoid aggressive driving habits, such as sudden acceleration and braking, as they can greatly affect fuel efficiency.

Using premium fuel in your Audi A4 can also improve fuel efficiency. The higher octane level of premium fuel can provide better performance and fuel economy. However, be sure to check your owner's manual to see if your specific model requires premium fuel.
